Guys is it possible that I create a program that allows you to open a file, then if you click the button labelled "Properties", it will open the properties window for the file selected. This is so that you won't have to go to the file, right-click it, then select Properties.
Hope you get what I mean

Yes it is. I converted pieces of C# code I found on the net to this class. It does nothing except open the Files' Right-Click Properties Dialog window. As far as reading and writing to and from it I think M$ is keeping it a secret or we need to learn C/Assembly code to get at the meta-data. All I have been able to do is read them using Shell32 Namespace.

Imports System.Runtime.InteropServices

Public Class SHOW_PROPS

  Public Const SW_SHOW As Short = 5
  Public Const SEE_MASK_INVOKEIDLIST As Short = 12

  Private m_fileName As String
  Private m_handle As IntPtr

  Public Sub New(ByVal fileName As String, ByRef hndl As IntPtr)
    m_fileName = fileName
    m_handle = hndl
    Call ShowProperties()

  End Sub

    Public cbSize As Integer
    Public fMask As Integer
    Public hwnd As IntPtr
    <MarshalAs(UnmanagedType.LPTStr)> Public lpVerb As String
    <MarshalAs(UnmanagedType.LPTStr)> Public lpFile As String
    <MarshalAs(UnmanagedType.LPTStr)> Public lpParameters As String
    <MarshalAs(UnmanagedType.LPTStr)> Public lpDirectory As String
    Dim nShow As Integer
    Dim hInstApp As IntPtr
    Dim lpIDList As IntPtr
    <MarshalAs(UnmanagedType.LPTStr)> Public lpClass As String
    Public hkeyClass As IntPtr
    Public dwHotKey As Integer
    Public hIcon As IntPtr
    Public hProcess As IntPtr
  End Structure

  <DllImport("Shell32", CharSet:=CharSet.Auto, SetLastError:=True)> _
      Public Shared Function ShellExecuteEx(ByRef lpExecInfo As SHELLEXECUTEINFO) As Boolean
  End Function

  Private Sub ShowProperties()

    sei.cbSize = Marshal.SizeOf(sei)
    sei.lpVerb = "properties"
    sei.lpFile = m_fileName
    sei.nShow = SW_SHOW
    sei.hwnd = m_handle

    Catch ex As Exception
      MsgBox(ex.ToString & vbCrLf & ex.StackTrace.ToString)
    End Try
  End Sub

End Class

Call it like this from your button click event;

Dim sp As New SHOW_PROPS(m_fileName, CType(Me.Handle, IntPtr))
